JOSEPH P. BASS, OF BANGOR, MAINE.

MACHINE FOR BURNISHING PHOTOGRAPHS.

SPEGIFICATION forming part of Letters Patent No. 243,349, dated June 28,1881.

Application filed May 9,1881. (No model.)

To all whom it may concern:

Be it known that I, J OSEPH P. BASS, of Bangor, in the county ofPenobscot and State of Maine, have invented certain new and usefulImprovements in Machines for Burnishing Photographs and Like Articles;and I do hereby declare that the following is a full, clear, and exactdescription of the invention, that will enable others skilled in the artto which it appertains to make and use the same, reference being had tothe accompanyingdrawings,forming a part of this specification, in whichFigure 1 shows a side elevation; Fig. 2, a detail of the post; Fig. 3,modification, partially in section.

Same letters show like parts.

My invention consists of an improved burnishing-machine for photographs,850., of that class in which the article to be burnished is fed over anon-rotating burnishing-tool by means of a feeding-roll.

The object of my invention is to enable the feed-roll to be readilyremoved from its position over the burnishing-tool when the same isbeing heated, thereby obviating any danger of condensation or moistureupon the roll during the process, and also to provide an easy method ofremoving the roll from the machine when repairs become necessary.

My invention will be understood by reference to the accompanyingdrawings, in which is shown an ordinary burnishing-machine of the classnamed, having base a, posts I) 1), adjusting device 0, burnishing plateand tool (I, and roll 0, with its crankf. The journals {1 h of themachine carrying the feed-roll in my improvement are not made a part ofthe posts I) b, as usual; but one of said journals, g, at one end of theroll, is attached to its post by a hinge or joint, while theotherjournal forms with its post a lock-joint, by which the roll issecured in position when in use.

One form of my invention is shown in Fig. 1. In this the journals areprovided with projections l l, fitting slots at in the posts I), andsecured therein by pins 12, passing through holes in both posts andprojections, the pin securing the journal 9 serving as a joint or hinge,enabling the roll to be elevated to a perpendicular position, while thepin securing the journal It operates to lock it in position when in use.(See detail.)

A modification of my invention consists in constructing the projectionof the journal '9 in the form of a stud round in cross-section,projecting downward, and fitting a round hole in the top of the post I).This stud, being secured in said post in such a manner as to permit itsturning therein, forms a vertical joint or pivot at one end of thefeed-roll, permitting said roll to be swung laterally from its positionover the roll. The lock may be substantially the same as beforedescribed, allowance being made for the difference in the action of thehinges orjoints.

I do not desire to limit myself to the precise construction of thehinges or locking devices herein described, as the details may be variedwithout departing from the spirit of my invention. When the locking-pinhas been removed and the roll swung away from the plate, its arbor canbe readily withdrawn from thejournal g, detaching it from the machine,and enabling it to be sent away for repairs. The handle can be removed,as usual, freeing it from the arbor It, which, when removed, leaves theroll entirely detached from any other part of the burnishing-machine.

\Vhat I claim as my invention is- 1. Ina burnishing-machine,thecombination of the burnishing-tool d with the feed-roll c, hinged orpivoted to the standards of said machine atone end, and provided with alocking device at the other extremity, substantially as and for thepurposes described.

2. In a burnishing-machine, the posts I) b, in combination with thejournals g h, carrying the feed-roll c, and provided with projections l,by which they are secured to said posts or standards, substantially inthe manner and for the purposes set forth.

In testimony that I claim the foregoing l have hereunto set my hand this5th day ot May, 1881.

Josnrn r. BASS.
